The supply equation for the Wilkinson washable computer keyboard is p=0.03x+80. Where x is the quantity supplied per month and p is the unit price in dollars.
a) find the points that would be used to sketch a graph of the supply curve
b) what is the lowest price (theoretically) at which the supplier will make a washable keyboard available in the market?
I am stumped for both a and b.
For a, how would I know which numbers to plug in for a? For example, I tried plugging in p=0.03(0)+80=80 for (0,80) but I don't know what numbers I can plug in for the remaining points. Can they be any number?
